Given numbers are 131,786,812,401

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 131,786,812,401 is 127965516.

Find LCM of 131,786,812,401 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

2 x 131 x 1 x 3 x 406 x 401 = 127965516

Therefore, the lowest common multiple of 131,786,812,401 is 127965516.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

131 x 786 x 812 x 401 = 33526965192

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

131 : 1, 131

786 : 1, 2, 3, 6, 131, 262, 393, 786

812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812

401 : 1, 401

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 131,786,812,401, is 1.

Now, the common factors can be found like this.

131:131

786:2x 3x 131

812:2x 2x 7x 29

401:401

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 131 = 262

Therefore, the value for common factors is 262.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 33526965192/(1x262)

LCM = 33526965192/262

LCM = 127965516

Thus, we can understand that the LCM of 131,786,812,401 is 127965516.
